The main purpose of the status window is to give various instructions to the user. When the user starts a tool, the window instructs how to perform the basic steps of the tool. However, because of space limitations, such information is shown in a compact form.
The window also shows a progress indicator during time consuming operations. For example, when ray trace rendering a view window, the progress indicator starts showing rendering time statistics. The Cancel button is also enabled and pressing it cancels the rendering.
